Lime suspension and limewater preparation

Indicative lime saturator sizing: lime quality, suspension concentration, saturated limewater production and approximate calcium increase in treated water.

Lime saturator

This calculator provides an indicative lime saturator check: from lime quality and suspension dosing it computes Ca concentrations, assesses if the limewater is saturated and estimates the resulting calcium increase in treated water.
